Kemampuan Direct Current yang Diubah Menjadi Alternating Current dalam Menghambat Perkembangan Telur Nyamuk Aedes aegypti

---

Background:Pre-adult dengue vector is controlled through management of the environment and the use of insecticides, although they have not yet entirely reduced dengue cas es. Development of method to control dengue vector physically have been conducted using electric current device converting DC into AC current.
Methods: The study was conducted in three stages, aimed to find the effectiveness of the device applied with 8 electric current (A C) strengths, the application of time-contact of the current (8 kinds), and water volume (8 kinds) in the container of the device, in killing Aedes aegypti eggs.
Results: The results showed, the device could inhibit the development of Aedes aegypti eggs 86.7% at average. The most effective electric strength to kill 50% mosquitoes' egg was 1.2 volt. On the other hand, variation of time-contact application and water volume of the device did not influence the effectiveness of the device.
Conclusion: Since the device could not inhibit the development of Aedes aegypti eggs up to 95%, it was concluded that the AC device is not effective against aquatic stages (pre-adult) mosquito, and cannot be developed as adevice to control dengue vector.

Abstract
Background: Containers inside and outside the school building are breeding places for Dengue vector. Presence or absen ce of A. aegypti mosquito larvae in a container could be affected by the type, location, co lor, material, condition and volume of container lid. The purpose of this study was to determine the condition of container that affect the presence of A. aegypti mosquito larvae.
Methods: A cross sectional survey was conducted to collect mosquito larvae in primary schools in the district of Ogan Komering Ulu, South Sumatera Province with asingie larvae method.
Results: Mosquito larvae were found in 54% of surveyed-schools (54%), and mostly were Aedes aegypti larvae (91%). There was a significant correlation between dark and light color difJerences of the water container in the presence of mosquito larvae (P value = 0.017, CI 95% = 1.2 to 2.9). On the other hand, there was no significant correlation between difJerent types of containers, location of containers, material of containers, the container lid and the volume of water in a container in the presence of larvae.
Conclusion: There was a significant correlation between the difJerence in container 's color (light and dark) in the presence of Aedes aegypti mosquito larvae. It is recommended to have regular cleaning of the containers in order to prevent dirt or mosses covered the containers which will impress of being dark color.
Key words: dengue, Aedes aegypti, larvae, containers, school.
